I think that you get SBD only when STEEM price is is higher than SBD - true until recently.
SBD got as high as 10% higher and now about 3.4% higher than STEEM.
I have noticed this a week or two ago and changed my selection to 100% powerup since there is no SBD payout anyway.
It might be a good time to trade SBD for steem - I should have traded more when it was 10% higher @1.109 STEEM / SBD.
Perhaps there will be another chance to get STEEM before STEEM goes back up about the price of SBD.
thank you freedomshift, yes i think that is why, maybe they trying to make Steem higher than SBD
